My suggestion, if you are interested in getting into Modern, is to pickup the shock lands that they reprinted in Return to Ravnica and Gatecrash. They are staples for a modern mana base and they dropped in price and will stay down for the next few weeks until the new set, Theros, is released and impacts standard.
This makes no sense, in the future shocklands cannot but go down in price
Even so, seeing what god hands beat other god hands and realizing that no deck is invincible is a good mental exercise. Sure, there are aggro god draws that can kill you on turn 2, but they still fold to the right hate, and that hate has its own problems too. It's a deeper exercise than simply saying "Naya Blitz" because you then have to consider the entire meta. No one deck would beat every other deck.
What else apart from Terminus can beat Blitz? Sorry for my english
